Comprehensive Product Line
-
Tyton® Joint Pipe
The industry-standard push-on joint, offering a simple, sturdy, and watertight seal using a flexible rubber gasket. -
TR Flex® Restrained Joint Pipe
A factory-adapted, integrally cast restraint system that prevents joint separation under pressure—ideal for buried or above-ground installations. -
Mechanical Joint Pipe
The original modern joint design, using bolts, glands, and gaskets to create a secure, watertight seal—perfect for valves, fittings, and appurtenances. -
Fabricated Pipe & Appurtenances
Custom-fabricated ductile iron pipe with options for holes, taps, outlets, thread-o-lets, and flanged ends up to 48".
Advanced Linings, Coatings & Encasements
McWane Ductile offers a wide selection of interior linings and exterior coatings to meet project-specific requirements:
- Interior Linings: Cement mortar with bituminous seal coat, Protecto 401™, and specialized glass linings for abrasion and chemical resistance.

-
Tyton®Joint Pipe
Tyton® Joint Pipe: Simple. Sturdy. Reliable. The predominant gasket employed throughout the ductile iron pipe industry by several pipe manufacturers. Made of flexible and resistant rubber, the Tyton gasket provides a permanent watertight seal through radial compression provided by the pipe spigot within the finished joint.
-
TR Flex® Restrained Joint Pipe
Simply put, the most-widely accepted and installed integrally-cast restraint joint system in the ductile iron pipe industry. Proven as a versatile and easy-to-use item, this joint is flexible, sure, and watertight to and beyond its 350-psi pressure rating while preventing longitudinal separation of the joints whether installed above or below ground. TR Flex utilizes the Tyton joint gasket for a watertight seal along with a factory adapted spigot and extended bell casting to provide positive and permanent joint restraint.
-
Mechanical Joint Pipe
The "original" modern pipe joint, circa 1925; the mechanical joint remains in use primarily as a means for connecting fittings, valves, and similar appurtenances to a pipeline. The nuts, bolts, and gland featured in the joint provide a permanent watertight seal to 350 psi and more through a “stuffing box” compression of the gasket into its counterpart triangular recess of the joint.
-
Ball & Socket Joint Pipe
All the best of Tyton or Fastite rubber-gasket sealed ductile iron pipe joints with triple the maximum deflection available from either. Designed and used in subaqueous installations where lateral forces and an unsure bury condition demand a strong yet flexible restraint joint piping system. 15-degrees of deflection per joint equates to a 4-1/2 foot available offset in every full length of pipe laid or launched.
